TinI/O
is a tool for interfacing the Cypress CY7C65211 USB-Serial Bridge Controller and its GPIO.
1. How to build it
To set up TinI/O, you'll need:
- A linux machine (the processor architecture doesn't matter, but Debian or Ubuntu is almost guaranteed to work)
- an USB dongle with the chip
- a C and C++ compiler (GCC is most common)
- GNU Make and CMake
- libusb 1.0
You can build TinI/O by
a)cd-ing to the cylib/build directory and build the needed libraries with:
# cmake ..
# make
# sudo make install
Then go to the ../tinio directory and build and install TinI/O with:
# make
# make install
or
b) executing the autobuilder script in the main directory that will do the above for you.
NOTE: Although the autobuilder should be working in most use cases, it's still better to build the tools manually (if you have the needed knowledge, of course)
2. Getting started
Before you start using TinI/O, you have to reflash the target chip so it can be recognised by your PC. That is done with the supplied cy-config utility.
To reflash a chip, you'll need to navigate to /usr/share/tinio/flashes directory. There you'll find files that contain different flash images. (I'll say more about the images later in the chapter TODO)
For a general configuration (5 inputs, 5 outputs), we'll use TODO
You can get a quick summary on TinI/O by executing it.
# ./tinio
TinI/0 0.1
Usage:
tinio <options>
The supported options are:
-d<device number> - specifies the desired device - integer 0 to 15
-i<interface number - specifies the USB interface number - integer 0 to 255
-s<pin number> - sets the specified pin to the value specified with -v - integer 0 to 11
-r<pin number> - reads the specified pin's value and prints it to the stdout - integer 0 to 11
-v<value> - value for -s option - integer 0 to 1
-e - enables expert mode (enables protected pins)
